Well after steping a little on the tuneup im staring to push water again.As some know im on a copper o ring reciver groove setup.I would like to know how much power can you make before i shoud be pushing water?Seems like my power level is no were close enough to were im pushing water.Right now i push about a quart per pass and i get a little messy under the hood because it fills my reserve all the way up.My heads are torque to 100ft pounds but i belive i may have hurt a gasket due to not torquing them down tight enough on the fresh gaskets (85ft pounds) thinking about putting new gaskets in and trying it again.What do you guys think. BTW i did do the heat cycle and retorque after full cool down but were only torque at 85ft pounds.At that point we were leaking water pretty bad in the cylinders and we pulled the haeds cleaned it all up and did the 100ft pound torque.Can copper gaskets just get messed up on a inproper torque install.

What kind of HP is it now???

I was pushing the same as you right around 890rwhp... but im a Boosted car.....
The last time out i did lift both head gaskets and popped the drivers side gasket and am currently going to the same head gasket set-up[ you have now........
When i lifted both gaskets last time out i was a lil over 1Krwhp on GM MLS gaskets.......

"Can copper gaskets just get messed up on a inproper torque install."

This is not likely.

Check you spark plugs for detonation. It will look like tiny black specks with a magnifying glass. You may want to cut off the threads to expose the bottom of the porcelain. If you are relying on your ears or a knock sensor you are fooling yourself.

If you had it on a dyno it would show up by sending your blow by meter wild.

I would have to check back but I remember some guys pumping the cylinders with high pressure nitrogen to see where it will leak first.

Are you on L19 head studs? Whats the timing? I relocated the overflow to a catch can style. Water under the hood and slicks is not a good combo

tuff

Yes L19 studs timing is at 17 degrees.

Might be a little to much timing.

My ET heads dont like timing or hot plugs AT ALL.
What plugs are you using?


Shiz's car dint have any head lifting issues, we use cometic MLS, he has std. size L19's.

What gas are you using? C16?

Sounds like to much timming. like ATV said. Im not real sure on the original question of how much power. but mine has made 900 to the wheels with no lifting.

Are you sure its head lifting?
did you check the coolant?
do you have a stock water pump or electric?

Also I had a stock coolant cap go weak on me once. have you tried replacing it?

Tear it down. Copper Gaskets can and will push out if they are let loose from insufficient TQ.

I have the race electric pump and i have a 20psi radiator cap on it that was changed out.

NGK 9 is what im using for plugs and i only run C16 fuel.I have also heard that take timing out because it is not nessary with the et heads.How much timing have you taking out?Ive heard people go as low as 12 degrees but im thinking setting it at 15 degrees and sees what happens.

Tearing it down as i post this we don't wanna take any chances and its really not a big deal.Fresh gaskets will be here tomorrow.

what did the n20 make to the wheels and what jets?

How did the gaskets look????

tuff

iTrader: (15)

Gaskets were burn't between cylinders.Also the gaskets i feel are a tad on the big side and hang into the chamber a bit.Might be causing a hot spot on the gasket.I ordered gaskets a little bigger so it won't hanging in the chamber.

No. They are direct replacements. Just have the clamping force of a 1/2 stud. Timing wise for that big of a shot is a bit. But I would think with the 16 it would hold.

tuff

iTrader: (15)

No there standard size.I was told that there strengh was equal to a regular 1/2 stud.I am on a iron block if was aluminum i think the 1/2 would be the only way to go.

Hmmm ya got me wondering now......... they they make an L19 in a 1/2" stud???
If so it wouldnt be that hard to machine everything for it since my motor is out now.....

I run the same L19's I'm not saying you need 1/2" but by the 100ft/lbs i thought you had 1/2" Was your block done with the tq plate at 100 ft/lbs?

Eric told me to tq mine to 75 no more and there holding great. i would think if you over tq them you will get the boltpart of the head bowing in and the middle of the cylander on the head higher. but im no expert.
